Embodiment 1

[0030] Such as Figure 1-Figure 4 As shown, the present invention provides a protective device with a leaf spring structure, including two base plates 1 respectively used to fit the two surfaces of the auxiliary spring; the inner surface of the base plate 1 is provided with a wear pad 2, and the wear pad 2 Made of nylon material and covered on the outer surface of the leaf spring as a whole by means of adhesion, thereby improving the wear resistance of the outer surface of the leaf spring; both sides of the base plate 1 are provided with side covers that extend and cover the sides of the leaf spring 3. The side cover 3 is located in the middle of the side edge of the base plate 1; the base plate 1 and the side cover 3 are made of metal, and the plate spring is covered by the base plate 1 and the wear-resistant pad 2 to avoid direct contact between the plate spring and the U-bolt, thereby preventing the plate The wear of the spring effectively ensures that the axial clamping fo...

Embodiment 2

[0042] Such as Figure 4 As shown, this embodiment also provides a leaf spring structure, including the main spring 7 and the auxiliary spring 8, and also includes the above-mentioned protection device for the leaf spring structure. Fixing the main spring 7 and the auxiliary spring 8 through the protection device can effectively improve the wear resistance of the auxiliary spring and increase the service life of the entire leaf spring structure.

[0043] Wherein, the main spring 7 is formed by stacking a plurality of leaf springs; the secondary spring 8 is made of glass fiber and epoxy resin, and the main spring 7 is made of traditional leaf springs to ensure the bearing strength of the main spring 7. The auxiliary spring 8 is made of glass fiber and epoxy resin composite material, which greatly reduces the weight of the leaf spring structure and meets the production requirements for lightweight automobiles.

Abstract

The invention relates to the technical field of automobile suspension parts, in particular to a protection device of a plate spring structure and the plate spring structure. The protection device of the plate spring structure comprises two base plates used for being attached to the two surfaces of an auxiliary spring respectively. A wear-resistant pad is arranged on the inner surface of each baseplate. Side covers extending and covering the side edges of a plate spring are arranged on the two side edges of the base plates. A moving gap is reserved between the two side covers located on the same side. The protection device of the plate spring structure has the beneficial effects that the plate spring is covered with the base plates and the wear-resisting pads, the plate spring is preventedfrom making direct contact with a U-shaped bolt, therefore the plate spring is prevented from being abraded, it is effectively guaranteed that the axial clamping force of the U-shaped bolt cannot bereduced, and the service life of the plate spring is indirectly prolonged; and the side covers cover the side edge of the plate spring, lateral deviation between the base plates and the plate spring is effectively avoided, and meanwhile external foreign matter is prevented from cutting the side edge of the plate spring in the vehicle running process.

Description

technical field [0001] The invention relates to the technical field of automobile suspension components, in particular to a leaf spring structure protection device and a leaf spring structure. Background technique [0002] Suspension system refers to the entire support system composed of springs and shock absorbers between the vehicle body and tires. The proper function of the suspension system is to support the body and improve the riding experience. Different suspension settings will give the driver different driving experiences. [0003] As a traditional structure in the automobile suspension system, the leaf spring is a leaf spring composed of no less than one piece of spring steel. With the continuous development of technology, the main and auxiliary springs are used in the suspension system to cooperate; the main spring is used to connect the axle and the frame, and bear the supporting force, traction force, braking force and lateral force of the axle acting on the fr...
